ALBERT ATWOOD UNRUH, 0F PORTLAND, OREGON.

' CAR-FENDER.

To all whom it may concern:

Be it known that I, ALBERT A'rwooo UNRUH, a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Car-Fenders; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and'use the same.

This invention relates to improvements in car fenders.

One object of the invention is to provide a car fender having an improved means for automatically throwing the same into operative position when coming into engagement with an obstruction.

Another obj eat is to provide an improved construction and arrangement of rollers whereby the object struck by the fender will be conveyed or carried up onto the body portion of the fender and thus prevented from being injured by the fender.

A further objectis to provide a fender of this character which will be simple, strong and durable in construct-ion, efiicient and re liable in operation and well adapted to the purpose for which it is designed.

With these and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings: Figure 1 is a side view partly in sect-ion of the front portion of a car showing my improved fender applied thereto and swung to an oper ative depressed position; Fig. 2 is a similar view with the parts in an inoperative raised position; Fig. 3 is a top plan view of the fender with parts broken away and in section; Fig. 4 is an enlarged side view through the outer portion of the fender and the .trip roller with the parts in the position shown in Fig. 1; Fig. 5 is an enlarged detail perspective view of one of the operating levers and links for the side bars and operating bars of the fender.

Specification of Letters Patent.

Application filed May 15, 1913.

1 bearing Patented Feb. 3, 1.914. Serial No. 767,821.

My improved fender comprises pairs of longitudinally disposed roller supporting bars 1 which form the side members of the fender and in which are formed a series of passages 2 adapted to receive and revolubly support the journals or trunnions 8 of a series of receiving rollers 4: which are thus revolubly mounted between the side members or bars 1 of the fender.

In the outer end of the bars 1 are formed elongated bearing passages 5 in which are revolubly and loosely mounted the trunnions of two outer supporting and lifting rollers 6.

The bars 1 are pivotally connected near their inner ends to depending hanger bars 7 secured to the under sides of the car platform or other suitable support as shown. On the outer ends of the side bars 1 are formed bearing plates 8 in which are revolubly mounted the trunnions of a supporting roller 9 which when the fender is thrown down in an operative position is adapted to engage the ground and thus support the outer end of the fender. When the fender is thus thrown down by the engagement thereof with an obstruction, as will be hereinafter described, the engagement of the obstruction with the lifting rollers 6 in the outer end of the fender will force said rollers down into engagement with the supporting roller 9 whereby the movement of the latter will be imparted to the rollers 6 to operate the latter in the proper direction for lifting and forcing the object or obstruction up onto the receiving rollers 4c of the receiving platform.

The inner ends of the bars 1 are pivotally connected to the lower ends of short links 10, the upper ends of which are pivotally connected tooperating levers 11 fixed to the opposite ends of a rock shaft 12 journaled in suitable brackets 13 secured to the under side of the car platform or other support. The lower ends of the levers 11 are offset 7 to receive the links 10 of the side bars 1 and to the lower ends of the levers 11 are connected the inner ends of fender operating bars 14:, the outer ends of which are slidably engaged with guide clips 15 secured to the outer sides of the bearing plates 8. The outer ends of the operating bars 1a project beyond the ends of the side bars 1 and in the projecting ends of the bars 14 is revolubly mounted a trip roller 16.

Connected to the rock shaft 12 is a forwardly extending crank arm 17 to which is connected a retracting rod 18 the upper end of which is connected to a hand lever 19 pivotally secured to the front end of the car at a suitable position to be grasped by the motorman or operator for the purpose of restoring the fender and its operating mechanism to their normal raised positions. The

receiving and operating rollers of the receiving platform are preferably covered with rubber or similar yielding material which will also cause the rollers to obtain a firm grip on the obstruction, or the latter to be engaged by the fender, whereby said object is more readily lifted onto the receiving platform. The hangers 7 for the supporting bars 1 of the fender have connectedthereto suitable braces 20. The receiving rollers 1 are preferably braced and supported midway between their ends by a central longitudinally disposed connecting bar 1 through which the shafts of the rollers pass.

When in normal or raised position, the roller supporting bars and rollers are held in a substantially horizontal position by the lovers 11 and the links 10, and when in this position, the ends of the bars 1 1 which support the trip roller 16 extend forward in position to hold the trip roller some distance beyond the rollers 9 and 6 on the outer end of the fender. With the parts in this position, the trip roller 16 would first come into engagement with an obstruction and together with the bars 11 would be forced back, thus swinging the lever 11 to the posi: tion shoWn in Fig. 1, which movement of the lever would pull down the link 10, thus tending to straighten the latter, which action would swing the inner ends of the roller supporting bars 1 upwardly and the outer ends together with the rollers downwardly until the roller 9 was brought into engage ment with the ground. The engagement of the roller 9 with the ground would cause the roller to revolve, and the weight of the object struck by the trip roller 16 and the elevating rollers 6 will force these rollers into frictional engagement with the ground engaging roller 9, and said trip and elevating rollers will be revolved in the proper direction to raise or lift the object struck and to force the latter up over the receiving rollers 1 and into a place of safety on the fender. As soon as the obstruction has been removed the lever 19 may be swung upwardly, and through the rod 18 and crank arm 17 will swing the lever 11 forwardly,

which operation will restore the fender to its normal position.

From the foregoing description taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood with out requiring a more extended explanation.

Various changes in the form, proportions and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention as defined in the appended claims.

Having thus described my invention, what I claim is:

1. A car fender comprising hangers suitably connected to the end of a car, roller supporting bars pivotally connected near their inner ends to said hangers, a. series of receiving rollers revolubly mounted in said bars, lifting rollers pivotally and loosely mounted in the outer ends of the bars, a ground-engaging roller also revolubly mounted in the outer ends of said bars and adapted to be engaged'by said lifting rollers whereby the latter are operated when the fender is in depressed position, fenderoperating levers suitably connected to the car, links operatively connecting the inner ends of said roller-supporting bars of the receiving platform with said levers, a trip mechanism comprising a pair of fenderoperating bars pivotally connected at their lower ends to the inner ends of said levers and slidably supported at their outer ends on said roller-supporting bars, a trip roller revolubly mounted in the outer ends of said fender-operating bars whereby, when said trip roller is engaged with an obstruction, the fender-operating bars will be forced back and said levers thereby actuated to swing the outer ends of the fender downwardly in position to engage the ground roller therein with the ground, whereby said roller is revolved and the movement thereof imparted to the trip roller and lifting rollers of the fender.
